Apple iMac A1311 820-2784 is a laptop motherboard used in the Apple iMac A1311 and Apple MacBook Air A1466.

The catalog has 1 schematic, 1 boardview file and 2 BIOS files for it, posted between 2020 and 2023 across 3 Telegram channels. Each download button opens the original Telegram post.

The files are marked Rev A; other revisions of the same board can differ in parts and layout.

The boardview is packed in an archive and the file name does not say which format is inside; most open in OpenBoardView or FlexBV. What Is a Boardview File and Why You Need One lists the common formats.

With both a schematic and a boardview you can find a net on the diagram and then locate the same part on the board by its reference designator. No Boardview for Your Board? How to Work Without One shows the workflow.

Frequently asked questions

Which laptops use the 820-2784 motherboard?
File names in the catalog tie 820-2784 to the Apple iMac A1311 and Apple MacBook Air A1466. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of 820-2784 do I have?
Files for this board mention Rev A. The revision is printed on the PCB silkscreen, usually next to the board code. Pick files with the same revision when you can; if yours is not listed, the closest revision is usually fine for the schematic but check part positions in the boardview carefully.
How do I open the 820-2784 boardview file?
The 820-2784 boardview comes inside an archive whose name does not state the format. Unpack it and check the extension; most laptop boardviews open in OpenBoardView or FlexBV. See What Is a Boardview File and Why You Need One.
What should I check before flashing the 820-2784 BIOS?
Read the original chip with a programmer and save two copies before writing anything. A dump from another board carries that board's serial number and MAC address, so restore yours from the backup.
